Afghan President Hamid Karzai became emotional during a speech on human rights on Sunday, crying and taking long pauses as he described how Afghan children are being killed by terrorists from Pakistan and in bombing raids by NATO and the US-led coalition. "We can't prevent the terrorists from coming from Pakistan, and we can't prevent the coalition from bombing the terrorists," he said during a speech,"and our children are dying because of that." Karzai paused and wiped both eyes with a white handkerchief. Then a single tear rolled down his right cheek and bounced off his suit lapel.
